jdk.awt.image.RenderedImage — clojure-interop/java.awt 1.0.5

RenderedImage is a common interface for objects which contain or can produce image data in the form of Rasters. The image data may be stored/produced as a single tile or a regular array of tiles.

copy-data clj

(copy-data this raster)

Computes an arbitrary rectangular region of the RenderedImage and copies it into a caller-supplied WritableRaster. The region to be computed is determined from the bounds of the supplied WritableRaster. The supplied WritableRaster must have a SampleModel that is compatible with this image. If raster is null, an appropriate WritableRaster is created.

raster - a WritableRaster to hold the returned portion of the image, or null. - java.awt.image.WritableRaster

returns: a reference to the supplied or created WritableRaster. - java.awt.image.WritableRaster

get-color-model clj

(get-color-model this)

Returns the ColorModel associated with this image. All Rasters returned from this image will have this as their ColorModel. This can return null.

returns: the ColorModel of this image. - java.awt.image.ColorModel

get-data clj

(get-data this)

(get-data this rect)

Computes and returns an arbitrary region of the RenderedImage. The Raster returned is a copy of the image data and will not be updated if the image is changed.

rect - the region of the RenderedImage to be returned. - java.awt.Rectangle

returns: the region of the RenderedImage indicated by the specified Rectangle. - java.awt.image.Raster

get-height clj

(get-height this)

Returns the height of the RenderedImage.

returns: the height of this RenderedImage. - int

get-min-tile-x clj

(get-min-tile-x this)

Returns the minimum tile index in the X direction.

returns: the minimum tile index in the X direction. - int

get-min-tile-y clj

(get-min-tile-y this)

Returns the minimum tile index in the Y direction.

returns: the minimum tile index in the X direction. - int

get-min-x clj

(get-min-x this)

Returns the minimum X coordinate (inclusive) of the RenderedImage.

returns: the X coordinate of this RenderedImage. - int

get-min-y clj

(get-min-y this)

Returns the minimum Y coordinate (inclusive) of the RenderedImage.

returns: the Y coordinate of this RenderedImage. - int

get-num-x-tiles clj

(get-num-x-tiles this)

Returns the number of tiles in the X direction.

returns: the number of tiles in the X direction. - int

get-num-y-tiles clj

(get-num-y-tiles this)

Returns the number of tiles in the Y direction.

returns: the number of tiles in the Y direction. - int

get-property clj

(get-property this name)

Gets a property from the property set of this image. The set of properties and whether it is immutable is determined by the implementing class. This method returns java.awt.Image.UndefinedProperty if the specified property is not defined for this RenderedImage.

name - the name of the property - java.lang.String

returns: the property indicated by the specified name. - java.lang.Object

get-property-names clj

(get-property-names this)

Returns an array of names recognized by getProperty(String) or null, if no property names are recognized.

returns: a String array containing all of the property names that getProperty(String) recognizes; or null if no property names are recognized. - java.lang.String[]

get-sample-model clj

(get-sample-model this)

Returns the SampleModel associated with this image. All Rasters returned from this image will have this as their SampleModel.

returns: the SampleModel of this image. - java.awt.image.SampleModel

get-sources clj

(get-sources this)

Returns a vector of RenderedImages that are the immediate sources of image data for this RenderedImage. This method returns null if the RenderedImage object has no information about its immediate sources. It returns an empty Vector if the RenderedImage object has no immediate sources.

returns: a Vector of RenderedImage objects. - java.util.Vector<java.awt.image.RenderedImage>

get-tile clj

(get-tile this tile-x tile-y)

Returns tile (tileX, tileY). Note that tileX and tileY are indices into the tile array, not pixel locations. The Raster that is returned is live and will be updated if the image is changed.

tile-x - the X index of the requested tile in the tile array - int tile-y - the Y index of the requested tile in the tile array - int

returns: the tile given the specified indices. - java.awt.image.Raster

get-tile-grid-x-offset clj

(get-tile-grid-x-offset this)

Returns the X offset of the tile grid relative to the origin, i.e., the X coordinate of the upper-left pixel of tile (0, 0). (Note that tile (0, 0) may not actually exist.)

returns: the X offset of the tile grid relative to the origin. - int

get-tile-grid-y-offset clj

(get-tile-grid-y-offset this)

Returns the Y offset of the tile grid relative to the origin, i.e., the Y coordinate of the upper-left pixel of tile (0, 0). (Note that tile (0, 0) may not actually exist.)

returns: the Y offset of the tile grid relative to the origin. - int

get-tile-height clj

(get-tile-height this)

Returns the tile height in pixels. All tiles must have the same height.

returns: the tile height in pixels. - int

get-tile-width clj

(get-tile-width this)

Returns the tile width in pixels. All tiles must have the same width.

returns: the tile width in pixels. - int

get-width clj

(get-width this)

Returns the width of the RenderedImage.

returns: the width of this RenderedImage. - int
